Thanks for your question and for taking the time to give a link to an example page as well as a detailed explanation of your problem.
As far as I can see you have done everything correctly. I set up the IPTC/EXIF mapping rule just as you described (leaving the IPTC Value set to “- None (select a value) -“). I copied five of your PDF documents into the Media Library on my test system and the Caption field was set correctly. For example, your 2011-09-13-BurialRegulations file has a Caption of “Burial Regulations”.
I also clicked the “Map All Attachments, Standard Fields Now” button and all of the items in my Media Library were updated as expected. In some cases, a prior value was replaced by the new value.
Have you added “Caption” as a column of your Media/Assistant submenu table to verify the content of that field?
Have you tried using the Bulk Edit area “Map IPTC/EXIF metadata” button or the Media/Edit Media “Map IPTC/EXIF metadata” link to update one or a few items?
I am not sure what else to suggest. Any additional information you can provide would be most helpful.
David, hi sorry in not replying sooner I was off.

Found it – in the EXIF/Template: template:([+pdf:Title+]) there was a spurious tab? character so the “template:([+pdf:Title+])” string appeared in the middle of the entry field. I don’t know how it got in there but I just put the cursor to the left of the template and pressed delete and it went. Everything is now working fine.
I think I must have used Word at some point because if you have tab followed by template:([+pdf:Title+]) and somehow select the whole line then the tab character gets pasted into the MLA EXIF mapping field along with the template:([+pdf:Title+])
Thank you for your update with the excellent news and for your detective work.
Tabs and spaces are allowed in custom field names, so they are significant in the substitution parameter values as well. It’s hard to spot this kind of trouble in the midst of a custom template.
I am marking this topic resolved, but please update it if you have any problems or further questions regarding the topic.
